A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Detecting Network Attachment Working Group of the IETF. Title : Detecting Network Attachment in IPv6 Networks (DNAv6) Author(s) : J. Kempf Filename : draft-ietf-dna-protocol-03.txt Pages : 61 Date : 2006-10-24 Efficient detection of network attachment in IPv6 needs the following three components: a method for hosts to detect link change in the presence of unmodified (non-DNAv6) routers, a method for the host to query routers on the link to identify the link (Link Identification) and a method for the routers on the link to consistently respond to such a query with minimal delay (Fast RA). Solving the link identification based strictly on RFC 2461 is difficult because of the flexibility offered to routers in terms of prefixes advertised in a router advertisement (RA) message. Similarly, the random delay in responding to router solicitation messages imposed by RFC 2461 makes it difficult to receive an RA quickly. In this memo, a mechanism that requires the hosts to monitor all the prefixes advertised on the link and use it for link identification in the presence of non-DNAv6 routers is presented. A more efficient link-identification mechanism requiring the DNAv6 routers to monitor the link for advertised prefixes to assist the hosts in link identification combined with a fast router advertisement mechanism that selects the order of response for the router deterministicly is also presented.

Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-dna-protocol-03.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
